WILLIAM BIRTVVISLE, OF HARTFORD, ENGLAND.

M'OWING OR REAPING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 690,229, dated December 31, 1901.

Application filed August 2, 1899. Serial No. 725,872. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM BIRTWIsLE, a subject of the Queen of Great Britain, re-

siding in Hartford, in the county of Chester,

England, have invented certain new and useful Improvements in Mowing or Reaping Ma.- chines, (for which apatent was granted to me in Great Britain, No. 7,880 of 1899,) of which the following is a specification.

This invention relates to the class of mowing and reaping machines which have reciprocating cutter-bars or knife-bars; and it has for its object to improve the mountings and structure appertaining to the said knife-bar.

and its operation.

Referring to the accompanying drawings, Figure 1 is an end elevation of a portion of a mowing-machine, showing one way of carrying out myinvention. The boss E and its pin and the connecting-rod D are omitted from this view. Fig. 2 is a plan view thereof, but showing the boss E and its pin and the connecting-rod. Fig. 3 is a plan of the knife head detached from the bracket forming the guideway, &c. Figs. 4 and 5 illustrate details to be hereinafter described. Fig. 6 is a View similar to Fig. 1, with the parts so arranged that the bracket on which the knife-head slides can be secured to the shoe of the machine; and Fig. 6 is a horizontal section of the parts seen in Fig. 6 in the plane'of the axes of the bosses c and E. Fig. 7 is an end elevation, enlarged, showing another way of carrying out the invention; and Fig. Sis a side elevation thereof, which is the one I at Figs. 9 and 10 are an end elevation and a side elevation, respectively, illustrating another form of the invention. Figs. 11 and 12 are respectively an enlarged side and end elevation of the knifehead shown in Figs. 9 and 10.

0' bearing directly on the surface of the bracket I may insert a liner H, as shown in Figs. 1 and 5, the latter showing the liner detached. This liner can readily be replaced by another when it becomes worn. The coverplate G has a pendentlip, which takes over the guide-piece C, and is provided with an oil-receptacle I, (seen best in Fig. 4, which shows it on a large scale,) having raised portions g, over which the oil-splashes, from the jarring produced by the reciprocating parts of the machine, to the holes G in the plate G and to the knife-head. J is a lid to the oil-container. In Fig. 6 the arrangement of the parts F and G being slightly dilferent from that seen in Fig. 1, these parts are designated, respectively, F and G In Figs. 7 and 8 the liner H may be dispensed with and the top or cover G instead of being bolted to lugs on the bracket F from the top, as shown in Figs. 1 to 6, is bolted at the side, the lugs being dispensed with and the l ugs on the cover bent or otherwise formed, as shown, to enable the bolts to pass through them and through the upright portion of the bracket from the side. The bolt-holes in the bracket may be elongated obliquely in order to regulate the amountof space between the top of the bracket F and the cover G Wherein the guide-piece of the knife-head slides.

Figs. 9 and 10 show another arrangement, in which the bracket F and the cover G are formed in one piece, and in this case also the liner may be dispensed with. Anadditional L-shaped piece K is provided, on which the sliding piece 0' bears. The height of this L- shaped piece K can be regulated by having inclined projections M on the bracket F along which the piece K can slide, corre-.

IOG

ferring more particularly to Figs. 2, 3, and 11, the swiveling finger device before referred to consists of a tapered pin P, having a wing P projecting at right angles to such distance.

that when the pin P is turned around the wing P will take position in front of the end of the connecting-rod D and keep it in position. The shank p of pin P fits into a tapered hole in the boss or enlargement E on the knife-head and is screw-threaded at the end to receive a nut R, which fits in a recess S in the head 0 in such a manner as to prevent its turning. The spring T bears against the nut, and therefore if the Wing be turned so as to take over the front of the end of the connecting-rod D, as shown in Fig. 2, the tapered shank p will be drawn into the tapered hole by the spring and will be held in such position by friction. The spring T is only to produce friction on the tapered pin to prevent it from turning too easily, and it is not an absolutely essential feature. It will be seen by referring to Fig. 10 that an outlet T is provided at the end of the cover G3 for the removal of dirt from the passage or way in which the guide 0 plays.

In some machines it may be necessary or desirable to fix the bracket or support F to the shoe of the machine. Fig. 6 shows how this may be done by reversing the position of some of the parts.

Having thus described my invention, I claim- 1. In a mowing or reaping machine,the combination with the shoe,the knife or cutter bar, and the connecting-rod, of the knife-head provided with a boss to receive the connecting-rod end, and with a laterally-projecting guide-piece above said boss, a support carried by the shoe on which said guide-piece slides, and a top piece or cover inclosing said guide-piece,means for lubricating said guidepiece, and a swiveling catch held in position in front of the connecting-rod end by means of friction.

2. In a mowingor reaping machine,the combination with the shoe, the knife or cutter bar, the connecting-rod, and the knife-head provided with a boss which forms a bearing for the connecting-rod end of the knife-head and with a laterally-projecting guide-piece elevated above said boss, a support for the knifehead, carried by the shoe and providing a sliding surface for said guide-piece, provided at its top with a laterally-projecting coverpiece which extends over the guide-piece and has a pendent lip, said cover-piece being secured to said support, whereby an inclosed guideway is formed for the guide-piece on the knife-head to protect it against dust, and means for introducing a lubricant to said guideway.

3. In a mowing or reaping machine, the combination with the shoe, the knife or cutter bar, and the connecting-rod, of the knife-head, in which the connecting-rod end has a bearing, said knife-head having a laterally-projecting guide-piece, and parts carried by the shoe which form a guideway for said guide-piece.

4. In a mowing or reaping machine, the combination with the shoe, the knife or cutter bar, and the connecting -rod for operating said knife, of a knife-head having a laterally-pro jecting guide-piece mounted on its top, a bracket mounted on the shoe and forming a sliding bearing for the said guide-piece and a covering having a pendent lip secured to the bracket/the bracket and covering forming an inclosed guideway in which the guidepiece plays.

5. In a mowing or reaping machine, the combination with a knife-head, provided with a bearing for the connecting-rod end, and the said connecting-rod, of a conical pin, having a bearing in the knife-head and provided with a wing at its-outer end which projects laterally over the-connecting-rod end and holds it in position on the knife-head, the nut on said pin, and means which prevent the nut from turning, whereby, as the wing is brought over the connecting-rod end it is screwed into the nut and holds itself snugly up to the connecting-rod end.

6. In a mowing or reaping machine, the combination with a knife-head, provided with a bearing for the connecting-rod end, and the said connecting-rod, of a conical pin, having a bearing in the knife-head and provided with a wing at its outer end which projects laterally over the connecting-rod end and holds it in position on the knife-head, the nut on said pin, the spring between the nut and boss, and means which prevent the nut from turning, whereby, as the wing is brought over the connecting-rod end it is screwed into the nut and holds itself snugly up to the connecting-rod end.

7. In a reaping or mowing machine, the combination with the bracket, and the guidepiece 0 of the knife-head, of the cover-plate G, provided with an oil-receptacle I, divided into three sections by two transverse ribs g, and with oil-holes G through the plate in the two outer sections of the receptacle, a space being left between the said ribs g and the top of the oil-receptacle so that the oil may pass over the ribs, substantially as and for the purposes set forth.

In witness whereof Ihave hereunto signed my name, this 11th day of July, 1899, in the presence of two subscribing witnesses.

WM. BIRTWISLE.
